Question for you guys.
I have a can of LT-32 not being used. I want to use it in the .358 Win. My target load, 180's at around 2,500 fps.
I researched .308 data, as there isn't much LT-32 data available. And, I know it's a niche type, specialty powder. But, I have a can and wanna use it.
I found .308 load data showing loads falling between Rl-7 and H-322, both good .358 Win powders with lighter bullets. By aiming for 2,500 with 180's, I'm well below max, generally around starting.
41 gr. RL-7 and 46 gr. H-322 will push 180's at 2,450 or so in the .358 Win. .308 data for various weight bullets puts LT-32 loads about half way between RL-7 and H-322 for approximately the same velocities.
I'm gonna split the difference, try 43.5 gr LT-32 with these FTX 180's and Speer FP 180's in the .358 Win.,which should run a bit short of 2,500 fps. LT-32 burn rate is between RL-7 and H-322, so that seems to make sense.
Because it's in the starter range, not pushing the envelope, I think it'll work out OK. It could be a while, thanks to all these hurricanes, before I get to check it out and report.
What ya think?
